An experiment is described in which a spatially periodic, time‐invariant electric field is used to create a spatially periodic cellular flow by the action of an electric shear stress in the region of a fluid‐fluid interface. The cellular motion is closely related to large‐amplitude interfacial deformations observed when an electric field stresses the interface between two fluids having nearly the same electrical conductivity. A simple theoretical model is developed for the cell streamlines, flow velocity, and distribution of electric potential, and this model is shown to be in agreement with the experimental observations.
